The old cam uses intake lobe number 7072, correct?

Here are the specs from the lobe catalog.
You’ll notice the lift at TDC spec is .141, if installed at 106.

The same as what you’re getting with the new cam.

Meaning, the V/P clearance at that point should be the same between the two.

Check the lobe lift between the two at the closest point(10ATDC?), they should still be within a few thou of each other.

As I said earlier....... you have yet to come up with anything that would point to why the new cam has way less clearance.
